CORN-PLANTER.

Application fi1ed Jun To all wiz m 1' t may concern 1 Be it known thatl,CHARLES /Voon GIL- Lesrm, a citizen of the United States, residing atEtna Green, in the county of Kosciusko and State of Indiana, haveinvented certain new and useful Improvements in Corn-Planters; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to improvements in corn planters.

One object of the invention is to provide a corn planter having animproved con struction and arrangement of seed depositing mechanism, andmeans attached to one of the wheels of the machine for periodicallytripping said mechanism and thereby discharging the seed in rows atequal distances apart.

Another object of the invention is to provide a seed planter havingmeans whereby the position of the deposited hills of seed will be markedwhen planted.

WVith these and other objects in view, the invention consists of certainnovel features of construction. and the combination and arrangement ofparts as will be more fully described and claimed.

In the accompanying drawings, Figure 1 is a side view of a corn plantershowing the application of the invention; Fig. 2 is a top plan viewthereof; Fig. 3 is a vertical longitudinal section through one of thehoppers and parts in rear thereof; Fig. 4 is a detail perspective viewof the rock shaft and the parts carried thereby; Fig. 5 is a detailperspective view of one of the trip devices and markers which areattached to and operated by one of the supporting wheels Referring moreparticularly to the drawings, 1 denotes the main supporting frame of themachine in which is revolubly mounted the axle 2 on one end of which isfixedly mounted a supporting and operating wheel 3, while on theopposite end is loosely mounted a supporting wheel 4. The side bars 5 ofthe frame extend forwardly and have pivotally connected to their outerends a supplemental frame 6 which carries the seed hoppers 7 anddepositing mechanism.

The hoppers 7 are secured to the ends of the frame 6 in any suitablemanner and are provided with revolubly supported bottoms or feed disks 8having therein series of seed Specification of Letters Patent.

pockets 9 which as the bottoms are revolved, are brought into registerwith a seed discharging passage 10 in valve plates 11 fastened tocastings 12 secured in the lower portion of the seed hoppers. The plates11 are fastened to the castings 12 by pivot bolts 13 on which thebottoms 8 revolve.

Secured to the plates 11 are seed discharge tubes 14 the lower ends ofwhich are connected with furrow opening runners 1.7 of the usual or anysuitable construction. In the rear ends of the runners 15 are pivolallvmounted seed discharging valves 16 which are adapted to close the lowerends of the tubes 14. The upper ends of the tubes lei are disposed belowthe discharge passages 10 in the plates 11 whereby when the seed isbrought around by the pockets 9 in the bottoms 8 to the passages 10 theseed will drop through from the pockets through said passages and intothe seed tubes from which said seed is discharged into the furrow at theproper time by the opening of the valve.

On the outer edges of the revolubly mounted bottoms 8 of the hoppers arebeveled gear rings 17 with which are engaged bevel gear pinions 18 onthe ends of an operating shaft 19 revolubly mounted in bearings in thesupplemental frame 6. On the shaft 19 is also fixed a sprocket gear 20which is connected by a sprocket chain 21 with a sprocket pinion 22 onthe axle 2 of the machine whereby when the axle is revolved by the wheel3, the movement thereof will be imparted to the shaft 19 and the latteris thus driven tooperate the revolving bottoms or plates of the hoppersas will be readily understood.

(in the main frame 1 are secured scat supporting bars 23 to one of whichis pivotally connected :1 bell crank lever 24 one end of which extendsupwardly and is provided with a handle within convenient reach of thedriver from the seat 25 on the upper ends of the bars 2;). The lever 24is provided with a pawl 26 adapted to be engaged with a segmental rack27 whereby the lever is locked in its adjusted position. The other endor arm of the lever 24 is connected by a short link 28 with the rear endof the draft tongue 29 of the machine. said tongue being secured to thesupplemental frame 6 whereby when the lever 24 is swung in one directionor the other the frame 6 will be rocked on its pivotal connection withthe outer ends
